Bosch GBH 240 F 0611273000 rotary hammer

New standard for drilling in hard materials

When a task requires fast and precise hole drilling in concrete, masonry, metal, or wood, not only the impact force but also the gearbox efficiency is key. The Professional series rotary hammer offers an impact energy of 2,7 J, allowing for effective penetration through the hardest concrete zones without excessive strain on the operator. Thanks to the optimized design of the gearbox housing, the tool achieves the fastest drilling speed in its class, which translates into real time savings during renovation or installation work. The motor power is 790 W, providing sufficient power reserve for performing advanced tasks even in difficult environmental conditions.

Working comfort and functionality for every task

The tool has been designed to reduce user fatigue during long working sessions. With a weight of 2,9 kg, it is one of the lighter models in its class, making it easier to work overhead or in hard-to-reach places. The ergonomic handle significantly reduces vibrations transmitted to the hand joints. The device offers wide functionality:

• Hammer drilling: ideal for concrete and masonry (maximum diameter 24 mm).
• Drilling without impact: for metal (up to 13 mm) and wood (up to 30 mm).
• Chiseling: thanks to the Vario-Lock system, the chisel position can be set at a 40-degree angle, facilitating the precise removal of ceramic tiles or mortar.
• Overload protection: the clutch prevents uncontrolled tool rotation in case of bit jamming, protecting the operator's wrist.

The ability to smoothly adjust the rotation speed and change the direction of rotation (left/right) provides full control over the drilling and bit extraction process.

Durability and ease of servicing

In a professional environment, downtime means lost money, which is why the design of this model emphasizes longevity and ease of repair. Approximately 85% of the device's parts are replaceable components, which facilitates servicing and extends service life even under intensive use. The tool is compatible with many dust extraction systems, which improves working conditions on the construction site and protects the mechanism from excessive concrete dust contamination. The set includes everything necessary to start working:

• Auxiliary handle for better stability.
• Depth stop (adjustable up to 210 mm).
• Replaceable SDS plus chuck and a quick-change chuck (for drilling without impact).
• Durable carrying case protecting the equipment during transport.

Key performance parameters include an impact energy of 2,7 J at a frequency of up to 4200 impacts per minute and a rotation speed adjustable in the range from 0 to 930 rpm. Such data allows for drilling holes up to 24 mm in diameter in concrete or even up to 68 mm using core bits, making the tool a universal solution for hydraulic and electrical installations. The tool meets rigorous safety standards and is intended for professional use, guaranteeing reliability for daily construction and renovation tasks.
